The use of "all" indicates that every single one of the log files is missing, and that this has come as a surprise to the speaker.
If you want to stay a bit more neutral, you could leave "all" out and simply ask

Wo sind die Logdateien, die in der Korrespondenz erwähnt sind?

Finally, "die ganzen" should also be understood, especially if emphasized correctly (emphasis in bold):

+1, though I think that "all die" does only indicate that a lot more files were expected, not that every single one is missing. If you expected hundreds of files and there were only a few, "all die" would still be fine.

I wouldn't worry about people understanding "die ganzen" as "the whole ones" - in fact this meaning would be highly unidiomatic. You'd probably say "die vollständigen" if you want to express this.

"Die ganzen ..." is the best way to translate what you want to say here. :)

[Jan's suggestion "all die Logdateien" is definitely correct and idiomatic - but when I try to picture someone saying this I see either someone trying to be funny (probably making a sad, bewildered face) or <disablepoliticalcorrectness> the stereotypical blonde </disablepoliticalcorrectness> - no offence meant, I just can't think of a more concise way to express what I want to say...
In a nutshell: "all die" is definitely marked usage]
